题目下面是4个形状,我看了答案了,但是不明白tessellate是什么意思。
图是我用画图功能做的,曲线应该是流畅,连贯的,就是表达个意思

感觉是D; 不一定对。
是什么年级的作业?

给点背景解释
A tessellation or tiling of the plane is a collection of plane figures that fills the plane with no overlaps and no gaps. One may also speak of tessellations of the parts of the plane or of other surfaces. Generalizations to higher dimensions are also possible. The tessellation is perhaps most well-known today for its use in the art of M.C. Escher.
In Latin, tessella was a small cubical piece of clay, stone or glass used to make mosaics. The word "tessella" means "small square" (from "tessera", square, which in its turn is from the Greek word for "four"). It corresponds with the everyday term tiling which refers to applications of tessellation, often made of glazed clay.

没理解这个单词的意思。
不过单看图形,其他三个都是四边形,只有B是五边形。
这是几年级的题啊?几何?
评论
请LZ公布答案
评论
Definition: tessellation is created when a shape is repeated over and over again covering a plane without any gaps or overlaps.
I think the answer should be B
评论
C长得像瓦片的家伙也有可能。
我在C和D中选
评论
完了, ABCD全有了,考到大家哗哗的一片人
评论
除了B之外,其他的图形都能向各个方向连续衔接,平铺延伸至整个平面

可能就是我们小时后去墙上扣的马赛克,那时候挺调皮的, 大致是这个形状的膜子
也只是我得猜想而已;)
评论
按这定义,应该是B
评论
强烈要求说说是几年级的作业,并过后来公布答案;)

现在小朋友的作业,挺玄的。。。。。。。无语一个

公布答案: b
MOTH,太强了,tessellateD的意思我是查了,就是不明白怎解啊。
题目是YEARS3-4的题目,适合年纪8-10AGES
评论
给palmer,moth,autraveler加分了。purpleme啊,没有分了,白条先吧
评论
想起前两天答的题,那天太晚没看答案,翻出帖子来看原来还加了分。谢啦!
不过我只能算是蒙对的,MOTH同志是强的!

C

Let me try to explain this. "Tesselatte" basically means "to cover a plane shape."
A plane shape means a 2D shape not a 3D shape. So to paraphrase the question,
it is probably asking:
"Which one of these shapes can be covered perfectly by repeated use of a single shape?"
Looking at all the options. It seems like the only 3D shape is B. Shape B cannot be tessellated.
The rest are all 2D shapes that can be covered with one 2D shape.
Shape B cannot be covered perfectly with one 2D shape.
"Covered perfectly" means shape B cannot be covered without 'gaps' or 'overlapping.'
If you were to cover shape B with one 2D shape, you would have overlapping paper.
I hope this helps.

嗯嗯 是B 这个就是考察镶嵌图案 边缘本身要有互补性
评论
很肯定地说C,就是能够像拼瓷砖一样拼起来,不会有缝隙。这种题OC考试会有,所以补习班三年级最晚四年级前半就会出现。
评论
您的意思是对的,不过可能我这个12年前的图画得太模糊,是指右上的那个图吗?
评论
这个单词的概念我女儿三年级的时候有问过我(记得好像是老师有教,可是她没明白),我同她哥分别(她哥只能英文)给她讲了,现在4年纪了理解了,没有问题
评论
看漏了NOT....应该是B,呵呵
评论
C、D我知道是可以拼,但是A我不明白怎么可以
评论
把A图形向右旋转180度,拼在原图型的正下方,就可以组成一个大的矩形,至于中间的锯齿部分是否完全互相补全,可能不太严谨,但可以大约认为上下锯齿吻合。
想对比的是B,铅笔型的尾部是个半圆,完全无法和其它图形吻合一致。
评论
香港的話
問題是:
哪個圖形不是密鋪圖案
答案應該是b
评论

12年前的挖坟贴
楼主家孩子二十几岁了。
评论
我觉得比较像B。理由是任意一点做切线都不会经过图形的内部。
-- 打完才发现是挖坟贴。
